Description
Technical field
The invention belongs to flux observation device technical field more particularly to a kind of static chamber flux observation device and gas production sides
Method.
Background technique
Currently, the prior art commonly used in the trade is such：In recent years, due to using climate warming as the whole world of main feature
Variation attracts extensive attention, and China is for CO2、CH4、N2The observational study of O isothermal chamber gas flux is more and more, including
To soil-atmosphere interface greenhouse gases flux observational study.Closed chamber method has equipment letter due to other opposite observation methods
List, flexible operation have pole convenient for carrying out the advantages that repeating and controlling experiment in Soil Trace Gases flux observational study
It is widely applied.The basic principle is that closed cabinet is covered on earth's surface, pass through the change of gas concentration at any time in observation cabinet
Change to calculate Soil Trace Gases discharge or absorption rate.
In order to keep experimental observed data accurate, observation case should completely cut off the gas exchanges inside and outside cabinet, and should be right before gas production
Gas is mixed well to reduce the contingency of gas collecting in cabinet, while should slow down temperature change in cabinet as far as possible.
Presently, there are following defects in static chamber observational study：(1) to realize, gas is sufficiently mixed in cabinet, in research mostly in cabinet
Interior installation fan, and with storage battery power supply.It is individually equipped with battery if each cabinet, then cost increases, while carrying significantly
It is inconvenient；If multiple cabinets share one piece of large-capacity battery, not only field traverse layout is cumbersome, inconvenient to carry, while observation point
The distance between be restricted, be unfavorable for selecting best observation point.Therefore, gas mixing is directly ignored in some observational studies,
To reduce the accuracy of observation to a certain degree.(2) injection is mostly used to be sampled in static chamber observation at present, way is
Gas is extracted with syringe, is then transferred to gas production bag or gas production bottle, during which needs to rotate gas circuit valve repeatedly, is operated more numerous
It is trivial, while large capacity syringe is mostly glassware on the market at present, is easily damaged when field carries.(3) in air-tightness side
Face mostly uses water sealed tank to realize the sealing between top box and base ring, not only increases base ring manufacturing procedure, and because field water intaking is tired
Difficulty, operation difficulty greatly increase.(4) cabinet closed period, since sunlight irradiates, the temperature of confined space is toward up in cabinet
It rises quickly, the temperature especially under summer direct sunlight in 30min internal box will likely be higher by 2~5 DEG C of temperature outside cabinet.And it is warm
Degree is one of main driving factors of greenhouse gases flux, thus, it is larger that temperature rises the result generation that cabinet may be made to observe
Error.Therefore, common way is that there is package the material of reflection and heat insulation effect (it is poly- such as to cover aluminium bubble chamber film, foam outside the enclosure
Styrene etc.).The material is not only easy to damage in the handling process of field, the aesthetics of device entirety is reduced, simultaneously as being wrapped
It is opaque to wrap up in material, observation case selection can only be confined to camera bellows.
In conclusion problem of the existing technology is：Existing technology in gas mixing, take gas, sealing, cabinet heat-insulated
Etc. existing defects, concentrate on operation convenience and observation accuracy in terms of there are larger contradictions.
Solve the difficulty and meaning of above-mentioned technical problem：The configuration of the present invention is simple, material are easy to obtain, side easy to operate
Just；The increased simple gas production external device of institute of the invention, integrates gas mixing and gas sample acquisition function, only needs simple operations
Air bag and triple valve can be achieved in cabinet that gas mixes and acquisition gas sample is to gas production bag or gas production bottle, without install fan,
It carries battery and uses syringe, enormously simplify the mixing of field gas and acquisition device；Designed specific sealing ring energy
It is enough to realize without water-stop without sealed cistern is arranged and carries sealing water；Using (transparent) heat insulation sun paint to camera bellows and bright
Case is thermally insulated, and can preferably maintain case body temperature, and avoids additionally wrapping up thermal isolation film outside cabinet, makes to open using glass box
Exhibition flux observation is possibly realized.The high-efficient effect of gas collecting of the present invention is good, is convenient for carrying, reusable, enormously simplifies
Gas collecting works when carrying out flux observation based on closed chamber method, time and labour saving, and improves the accuracy of observation.
